I SPRING-LEAF SEPARATOR;

State ofLOhio; have invented certain new and useful Improvements inSpring-Leaf Separators, of which the, following is a specification. T 1

Tl'llS invention relates to spring leaf separators, and the dev ce is anlmprovement in that class of tools having wedges or tapering jaws forseparating the leaves of a lam1- nated spring to permit oiling orlubrication thereof, substantially as herein shown and described andmore particularly pointed out in the claims. 7

In general, the object of this invention is to provide a simple andinexpensive tool adapted to assure proper entrance of apair of wedgesbetween any two adjacent leaves of a laminated spring and to permit aquick and convenient adjustment and a powerful action of the wedges toseparate the leaves without injury.

In the accompanying drawings, Figure 1 is a side elevation and sectionalview of my improved spring leaf separator in operating engagement with alaminated spring. Fig. 2 is a plan view of the device.

The separator comprises a yoke or U-shaped body 2, having two integralarms 3 and 4 of tapering form and wider at their base than at their endsto give strength and rigidity to the body and to resist the spreadingstrains at the outer ends of said arms which carry the wedges 5 and 6respectively. Wedge 5 is shown as an integral part of arm 3, whereas theother arm 4 is provided with a screw-threaded opening 7 in which a screw8 is mounted, and a handle 9 is provided at the outer end of said screwto rotate the same. The inner end of said screw has a threaded bore 10to receive and support the screw-threaded stem 11 of wedge 6,

and the external threads of the screw 8 and the stem 11 are made rightand left, or of different pitch, respectively, to cause an advancemovement of stem 11 relatively to screw 8. To make this differentialmovement possible before the wedge 6 is engaged with the spring S it isessential that rotation of stem 11 be prevented, which result isobtained by a round rod 12 slidably engaged Specification of LettersPatent.

within a passage 13 in arm 4: at a point he'- neath screw 8. Rod 12 hasright-angled 55. end'14 afhxed within the. shouldered-portion 15 ofwedge'6, and ther'od i s rela tively much: 'i longer than the stemll toaccommodate the: differential 'movemeiits of the screw and stem andstillrtainislidable engagementBO with arm 4. This"arrangement ofpartsaifords a wide range of adjustment of 'the' wedges to springs ofdifferent widths, and each adjustment may be obtained very quickly by arelatively few turns of the handle.

In applying the tool to the spring -S- it is esentiaLthat both wedgesshall come with their entering edges directly parallel and. opposite thesame parting line between any two superposed spring leaves and notopposite different parting lines. To facilitate this placement of thewedges, I mount a self-adjusting leveling member 16 opposite the wedges,said member having a stem 17 slidably splined within the body of yoke 2and provided with a coiled spring 18 about the stem to seat said memberagainst the spring S. A slight application of pressure will cause theleveling member to yield when it is engaged with either the top orbottom laminations of the spring and the operator is enabled to placeboth wedges with accuracy and despatch opposite any desired partingline, or in other words between any two adjacent spring leaves. Settingof the wedges at any desired parting line may be done by holding thebody of the device in one hand and separation of the leaves by thewedges is accomplished by rotating screw 8 with the other hand.

\Vhat I claim is:

1. A separator for a laminated spring, comprising a yoke having twooppositelyrelated wedges, means to advance one wedge in respect to theother, and means to aline the laminated spring parallelly with the saidwedges.

2. A separator for a laminated spring, comprising abody having arms eachprovided with a wedge, a movable support for one of said wedges and anadjustable leveling device mounted on said body opposite the wedges.

3. A spring leaf separator, comprising a yoke-shaped body having wedgesoppositely spring engaging said disposed and movably-related, and'aself-adjusting leveling device on said body opposlte said Wedges.

4. A separator for a laminated 5. A separator for a laminated spring,comprising a body having movably-related V Wedges, a leveling memberhaving a stem slidably seated within said body, and a member.

6. A' spring separator, comprising a yoke provided with a Wedge on onearm thereof,

a threaded opening on the other arm, an internally and externallythreaded sleeve mounted in such opening, a second Wedge, a threaded stemattached thereto and received. in said sleeve, and a guide slidablymounted Copies of this patent may be obtained for five cents each, byaddressing the"c ommissibner of Patents";-

one of said and a sprlng" in said yoke parallel to said stem andsleeveand attached vto said second Wedge to pre- 'ventthe same frcm rotating.

7. A separator forqa laminated-Spring compr sing a yoke, a-pair ofWedges a screw-threaded stem for one of said Wedges,

an" 'externally tln'eaded member mounted upon said yoke having-athreaded bore-to receive said stem and. the respective threads ofsaidmembers and stem being right-Fahd left threads, and a rod slidablyengaged with said yoke and aflixed :t0 the; Wedge having said stem, 1 l
